Seabed Morphology and Geomorphology Maps for Zeehan Marine Park

Seabed morphology and geomorphology maps for a subset area of Zeehan Marine Park in south-eastern Australia. The maps were derived from a 2-meter resolution bathymetry DEM compiled from a multibeam survey undertaken for Parks Australia by the University of Tasmania. A nationally consistent classification scheme and semi-automated GIS tools were used to map and classify key seabed features.

Use Cases

• Analyze seabed topographic highs, lows, and planar extents based on polygon geometry classifications.
• Characterize seabed geomorphology features based on bathymetry, backscatter intensity, and seabed imagery.
• Map the distribution of key seabed features using a nationally consistent classification scheme.
• Apply semi-automated GIS mapping tools (GA-SaMMT) for seabed characterisation workflows.

Strengths

• Derived from a 2-meter horizontal resolution bathymetry DEM.
• Uses a nationally consistent seabed geomorphology classification scheme.
• Incorporates supplementary data like backscatter intensity and seabed imagery where available.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific subset area of Zeehan Marine Park.
